[Intel-gfx] [PATCH 24/26] drm/i915: Decouple DP++ from the HDMI code
Ville Syrjala

Mon Feb 3 15:13:41 UTC 2020
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Decouple the DP dual mode adaptor stuff from the HDMI code so that
we can try to use it for DP branch downstream facing HDMI ports as
well.
